Answer:
Option D The negative number entered to signal no more input is included in the product
Explanation:
Given the code as follows:
- int k = 0;
- int prod = 1;
- while (k>=0)
- {
- System.out.println("Enter a number: ");
- k= readInt( );
- prod = prod*k;
- }
- System.out.println("product: "+prod);
The line 7 is a logical error. Based on the while condition in Line 3, the loop shall be terminated if k smaller than zero (negative value). So negative value is a sentinel value of this while loop. However, if user enter the negative number to k, the sentinel value itself will be multiplied with prod in next line (Line 7) which result inaccurate prod value.
The correct code should be
- int k = 0;
- int prod = 1;
- while (k>=0)
- {
- prod = prod*k;
- System.out.println("Enter a number: ");
- k= readInt( );
- }
- System.out.println("product: "+prod);
Answer:
ISO standards
Explanation:
ISO / IEC 14443 is the ISO standard that covers RFID usage by devices.
EPCglobal - Electronics Product Code Global Incorporated is also another international standard that covers RFID. These two standards work together to standardize RFID products produced by manufacturers so that these products can be the same across different markets and manufacturers. Example I can purchase a tag from one manufacturer and a transceiver from another and they would function well together. There are also other standards for RFID but the above two are the biggest and most popular with ISO being the oldest.
